COMPOSITION FOR TREATMENT OF CANCER WHICH IS PRODUCED FROM CANCER-TISSUE-DERIVED CELL MASS OR CANCER CELL AGGREGATE, AND PROCESS FOR PRODUCTION OF IMMUNOTHERAPEUTIC AGENT AND METHOD FOR EVALUATION OF EFFICACY OF IMMUNOTHERAPY BOTH USING THE COMPOSITION
COMPOSITION FOR TREATMENT OF CANCER WHICH IS PRODUCED FROM CANCER-TISSUE-DERIVED CELL MASS OR CANCER CELL AGGREGATE, AND PROCESS FOR PRODUCTION OF IMMUNOTHERAPEUTIC AGENT AND METHOD FOR EVALUATION OF EFFICACY OF IMMUNOTHERAPY BOTH USING THE COMPOSITION
Disclosed are an immunotherapy and a method for evaluating the efficacy of an immunotherapy, both of which utilize a novel cancer-tissue-derived cell mass (a cell mass derived from a cancer tissue) or a novel cancer cell aggregate which can reflect the in vivo behavior of a cancer cell accurately. A composition for treating cancer is prepared by chemically or photodynamically treating a cancer-tissue-derived cell mass or a cancer cell aggregate. The composition for treating cancer can be used as a cancer vaccine which is intended to be directly administered to a patient from which the cell mass or the cell aggregate is derived, or as a medicinal agent which is intended to be contacted in vitro with cells derived from blood collected from the patient. Further, the efficacy of an immunotherapy can be evaluated by measuring the activity of a killer T-cell in blood over time using a cancer-tissue-derived cell mass or a cancer cell aggregate.
